Back east in the hill country of KY, TN, WVA, VA,and GA. most of us hillbillys grew up ahuntin' squirrels with a 12 ga.. Low brass, 1 oz, loads in 4's,5's,or 6's would fill the bill, and usually you'd come awalkin' out of the woods with a "squirrel belt". Early on most of us were trying to put food on the table and that there 12, wether it be a single or one of the fancy doubles, would make sure there was something in the pot.
As for the guy shootin' off his finger, he didn't have much sense now did he!
